Numerical Investigations on Water-Ethanol-Diesel Emulsified Fuel

Abstract

The depleting oil resources and harmful emissions from fossil fuel have raised keen attention whole world wide. Emulsified fuel technology might prolong availability of earthborn fossil fuel along with the reduction of the pollutants. It may also be seen as a useful technique to meet the latest stringent Bharat Stage VI norms in diesel engine. Emulsification requires mixing fossil fuel with water in the presence of a surfactant. Oxygenated fuels like alcohols may also be blended due to its renewability. Oxides of nitrogen tend to reduce owing to cooling effect of water content in the emulsified fuel. At the same time decrease in the amount of particulate matter in the tail pipe was observed because of reduced molecule size of emulsified fuel. The combustion and exhaust emissions characteristics have been elaborated numerically with the help of simulation software in this chapter. Acceptability of emulsified fuels has also been highlighted for its use in compression ignition engines.
